BACKGROUND OF THE INVENTION

(a) Field of the Invention

The invention relates to a stool device having deodorization function,and more particularly, to a stool device having an appropriate routingpipeline for eliminating odor sources, thereby preventing disturbancescaused by a lavatory in use and ensuring good air quality in thelavatory.

(b) Description of the Prior Art

Excretion and defecation are natural physical activities of humanbeings. It is inevitable that excretion after biological reactions hasfoul smells and may even be as bad as unbearable due to diet reasons.Discomfort caused by such odors not only exists when one excretes in alavatory, but also incurs disturbances and irritations a subsequent userof the lavatory. The aforesaid occurrence is embarrassing for bothprecedent and subsequent users of the toilet. Although an exhaust fancan be installed in the lavatory to discharge air, it is yet unavoidablefor the user to bear the odors owing to a position of the exhaust fanand airflows. In addition, odors from excretion are likely diffused intoair, and thus the odors can only be gradually eliminated with a certainperiod of ventilation operation using the fan after excretion, meaningthat the subsequent user remains inescapable from the disturbances anddiscomforts caused by the odors. Having to confront torment by dailyphysical behavior, it is essential task of industrialist to provide asolution that effectively solves the aforesaid issues.

In view of the aforesaid issues of disturbances caused be excretionodors and unsatisfactory design of prior stools, the invention providesa stool device having deodorization function for offering better hygieneand comfort.

SUMMARY OF THE INVENTION

The primary object of the invention is to provide a stool device havingdeodorization function, in that the a stool device is capable of rapidlyeliminating foul smells and odors from excretion and defecation, therebypreventing disturbances when using a lavatory as well as maintaininggood air quality of the lavatory.

To accomplish the aforesaid object, a stool device having deodorizationfunction according to the invention comprises a stool body and adeodorizing device. The deodorizing device has an exhaust fan that drawsair from an air inlet via a routing pipeline, and an air inlet locatedat an appropriate position of the stool body and for rapidly drawingodors of excretion that is further discharged via the routing pipeline.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

To better understand objects, technical characteristics and effects ofthe invention, detailed descriptions shall be given with theaccompanying drawings below.

Referring to FIG. 1 showing a stool device having deodorization functionin a first embodiment according to the invention, the inventioncomprises a stool device 10 and a deodorizing device 20. The stooldevice 10 has a stool body 11, a water closet 12, and a seat 13 and astool cover 14 pivotally disposed at a rear seat plane 111 of the stoolbody 11. The seat 13 has a rear side thereof disposed with a protrudingedge 131 for closely joining with the stool body 11, so as to provide arear section of the seat 13 with optimal anti-pressure effects. Thedeodorizing device 20 has an air inlet 21 located at the rear seat plane111 of the stool body 11 and also at a front edge of a pivotal joint ofthe seat 13; a discharging channel 22 connected with the air inlet 21and located in the stool body 11; a discharging pipeline 23 incommunication and connected with the discharging channel 22, and locatedbetween a floor and a wall; an exhaust fan 24 disposed at an appropriateposition at an upper end of the discharging pipeline 23, and alsousually located at a ceiling; and a filter 26 devised at the air inlet26 and for preventing incoming of alien objects.

To put the stool device having deodorization function according to theinvention to use, the exhaust fan 24 is first activated to allow the airinlet with air drawing effects. When one is at the lavatory, odors ofexcretion in the stool body 11 are rapidly drawn by suction forces ofthe air inlet 21, and are discharged via the discharging channel 22 andthe discharging pipeline 23 in sequence. Not only a user is free fromdisturbances caused by the lavatory in use, but also a subsequent useris prevented from perplexities incurred by odors from a precedent user,thereby ensuring enhanced sanitary quality of the lavatory.

Referring to FIG. 2 showing a stool device having deodorization functionin a first embodiment according to the invention, the inventioncomprises a stool device 10 and a deodorizing device 30. The stooldevice 10 has a stool body 11, a water closet 12, and a seat 13 and astool cover 14 pivotally disposed at a rear seat plane 111 of the stoolbody 11. The seat 13 has a rear side thereof disposed with a protrudingedge 131 for closely joining with the stool body 11. The deodorizingdevice 30 has an air inlet 312 located at the rear seat plane 111 of thestool body 11; a discharging channel 32 connected with the air inlet 312and located in the stool body 11; a discharging pipeline 33 incommunication and connected with the discharging channel 32, and locatedbetween a floor and a wall; an exhaust fan 34 disposed at an appropriateposition at an upper end of the discharging pipeline 33; and a flat airinlet tube 31 in communication and connected with the air inlet 312,located behind the rear seat plane 111 of the stool body 11, having anair inlet opening 311 and serving for discharging odors from using thelavatory via the routing pipeline.

Referring to FIG. 3 showing a stool device having deodorization functionin a third embodiment according to the invention, the inventioncomprises a stool device 10 and a deodorizing device 40. The stooldevice 40 a stool body 11, a water closet 12, and a seat 13 and a stoolcover 14, wherein the seat 13 has a groove 132 at a rear lower edgethereof. The deodorizing device 40 has an air inlet tube 41 embedded atthe groove 132 of the seat 13. When the seat 13 is lowered, the airinlet tube 41 in form of a flat structure is located at the rear seatplane 111 of the stool body 11; and has a front end thereof providedwith an air inlet opening 411 for drawing odors from using the lavatory,and a rear end thereof provided with a flexible joint 412 for connectingto a discharging channel 42 of the stool body 11, wherein thedischarging channel 42 is connected with a discharging pipeline 43 andguided by a tube of an exhaust fan 44.

Referring to FIGS. 4A and 4B showing a stool device having deodorizationfunction in a fourth embodiment according to the invention, theinvention comprises a stool device 10 and a deodorizing device 50. Thestool device 10 has a stool body 11, a water closet 12, and a seat 13and a stool cover 14. The seat 13 has a lower rear side thereof disposedwith a sealed section 130, which is provided with an inlet groove 134 inform of an open groove at an inner side thereof and a groove opening133. The deodorizing device 50 has an air inlet tube 51 as a flatflexible tube. The air inlet tube 51 has an air inlet 511 at a front endthereof. The air inlet 511 is located at the groove opening 133 of theseat 13. When the seat 13 is lowered, odors from using the lavatory aresucked into the air inlet opening 511 via the inlet groove 134. The airinlet tube 51 has a rear end thereof in communication and connected withan air inlet opening 512, which is located at one side of the stool body11 and joined with a discharging channel 512 situated in the stool body11. The discharging channel 52 is in communication and connected withthe discharging pipeline 53 and drawn by an exhaust fan 54.
